Abstract
In response to a driver's braking request operation, for example, the driver's depression of a brake pedal, a hybrid vehiclesets a fraction of a regenerative braking torque by a motor MGand a fraction of a braking torque by a brake unitrelative to a preset braking torque demand Tr* according to the setting of a speed change ratio in a transmission(steps S, S, S, S, S, and S). The hybrid vehiclecontrols the motor MGto output the regenerative braking torque based on the preset braking torque demand Tr* and the set fraction of the regenerative braking torque, while controlling the brake unitto enable the braking torque based on the preset braking force demand Tr* and the regenerative braking torque by the motor MGto be applied in a distributive manner at a preset front-rear braking torque distribution ratio 'd' to front wheelsandand to rear wheelsand
